COMBINATION WHEEL AND CARRYING CHAIR.

Specification of Letters Patent.

Application filed February 14, 1912. Serial No. 677,550.

To all whom it may concern Be it known that I, TOWNSEND B. BALD- WIN, a citizen of the United States, residing at Edgewater Park,in the county of Burlington and State of New'Jersey, have invented certain new and useful Improvements in Combination \Vheel and Carrying Chairs, of which the following is a specification.

My invention relates to improvements in combination wheel and carrying chairs, the object of the invention being to provide a chair of this character which may be easily rolled so as to comfortably ride the patient, and. which may beeasily carried and maintained in level position while ascending or descending stairs.

A further object is to provide an im proved chair of this character which may be carried and elevated but a slight distance off the ground, so that the patient may be lifted over tracks and other uneven surfaces without the sensation of being unduly elevated.

A further object is to provide a chair of the character stated which may be dismantled and folded so as to occupy but comparatively small space so that it may be readily transported in a bag provided for the puro-se. p A further object is to provide a chair of this character which is designed for use primarily for travelers as it enables the chair to be carried in folded position, and may be adjusted and arranged to accommodate the patient under varying conditions which are apt to occur while traveling.

A further object is to provide a chair of this type which enables the patient to get into and out of the chair without any danger of the chair moving. I

With these and other objects in view, the invention consists in certain-novel features of construction and combinations and arrangements of parts, hereinafter described and pointed out in the claims. j

In the accompanying drawings: Figure 1, is a view inside elevation illustrating my improvements in position for carrying on the level. Fig. 2,is an enlarged detailed perspective view of the mounting of one of the chair legs. Fig. 3, is a sectional plan view taken on the line 3-3 of Fig. 1. Fig. 4, is a fragmentary view in transverse section showing the connection of the front axle and the platform mounting. Fig. 5, is a as will be more fully fragmentary view in sect-ion through one of the forward swinging clips. Fig. 6, is a fragmentary view in elevation illustrating a connection between the front handle bars and the hand holds 13, and Fig. 7, is a broken view illustrating the connection between the rear handle bars and the bar at the upper end thereof.

1, represents a platform to the under face of which, near its front end, a transverse axle 2 is secured by bolts 3, and these bolts at their upper ends, project through perforated ears 1 on the lower ends of an inverted U-shaped guide 5, preferably of sheet metal bent into the general form shown in Fig. 4. Rubber tired wheels 6 are mounted to turn on these axles at their outer ends, and together with swiveled caster wheels 7, secured to the under face of the platform near its rear end, permit the chair to be rolled over the ground. The swiveled casters 7 allow the chair to be readily swung around to any position, and as these casters are also preferably rubber tired, the chair will be practically noiseless. I

,On top of the platform 1, four socket pieces 8 are secured, and are adapted to receive the lower ends of a folding chair 9. This spreading movement of the legs of the chair is limited by braces 10, and this chair may be variously made to support the pa tient, but is preferably of the hinged or collapsible type illustrated, so as to occupy but small space when packed.

The guides 5 receive parallel bars 11 which. slide therein, and may be drawn out 2 and 3, or

to the position shown in Figs. they may be forced inwardly so as to lie at greater length upon the platform, and thus shorten, the length of the chair. These bars 11 are connected at their forward ends by a transverse bar 12, which projects at both sides beyond bars 11 to constitute hand holds 18. On the bars 11, 11. one board Patented June 25, 1912.

1 1 is fixed, and a second board 15 is connected to the first board by means of hinges 16, so as to constitute a foot rest. When this sliding foot rest is slid rearwardly, board 15 is swung over onto board 14, so as to permit the foot rest to be moved as far backward as desired. To further strengthen the foot rest, I provide two Lshaped clips 17 which have screwthreaded extensions 18 projecting through metal reinforced openings 19 in the platform and are held in place by bolts 20.

These clips are normally swung in position to project over the bars 11, but when the foot rest is shoved rearwardly, these clips are swung outward, so as to allow the foot rest to be moved until the board let strikes guides 5.

Angular guides 21 are secured on the platform 1 near its rear end to receive the for wardly projecting lower ends 22 of handle bars 23. These handle bars 23 have angle brackets 24 fixed to their rear faces, and adapted to be projected under platform 1. Pins 25 are adapted to be projected through openings in the ends 22 of handle bars 23 in front of guides 20, so as to prevent any rearward movement of the handle bars, and these pins are normally connected to the platform by chains 26 to prevent their loss.

Angular guides 27 are secured to the upper ends of the handle bars 23 for the reception of an angular handle 28 which is held against longitudinal movement by means of pins 29 fixed in the handle 27. This handle projects beyond the handle bars so as to afford a ready grip to move the chair about.

lVhen it is desired to carry the chair on the level, handle bars 30 are provided, and to. the lower ends of these handle bars, angle guides 31 are secured and adapted to receive the hand holds 13 and are secured thereon by removable pins 31*. On the upper ends of these handle bars, angle guides 32 are secured and receive a handle 33 which is long enough to project beyond the handle bars 30 and afford grips, whereby one person may grasp the handle 30 and another one the handle 27', so as to carry the chair without elevating it but slightly off the ground.

' On the rear faces of handle bars 23, angle guides 34 are secured, and are adapted to receive the handle 33, after the handle bars 30 are removed from bar 12. Thisarrangement of parts facilitates the carrying of the chair, and its occupant up and down stairs. For example, when ascending the stairs, the person in front will grasp handle 28, while the one in the rear will grasp hand holds 13, thus holding the platform in horizontal position. When descending the stairs, the positions will be reversed, and if after descending the stairs it is desirable to carry the patient on the level for a short distance, it is simply necessary for the one in the rear to grasp the handle 33, which we will suppose is in the angle guides 34.

To limit the outward. movement of the foot rest, a cross bar 35 is provided, and to guide the bars in their inward movement, small beads 36 are secured on the platform.

The wheels 6 may be easily removed by removing pins 37 which are connected by chains 38 with the shaft 2 to prevent their loss.

A great feature of this invention is that it permits the patient to step in and out of the chair without danger of the chair moving. By reference to. Fig. 3, it will be seen that an open space is provided between the board 15 and the platform 1, and the patient may place one foot through this opening onto the floor, and step into or out of the chair, holding the chair still in the meantime.

l/Vhen it is desired to pack the chair for transportation, it is simply necessary to disconnect the legs 9 from the sockets, fold the chair proper, slide the foot rest onto the platform and remove the handle bars so that the entire structure may be inclosed in a relatively small casing.

Various slight changes might be made in the general form and arrangement of parts described without departing from my in vention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
